Email clients are especially important for the business user but are useful even for those not dependant on a corporate email server. Even if you don't use them to check your email on a daily basis, they're handy to keep an offline backup of all your email in case of problems with the service.

For example, choose Has Attachment to limit your search to messages with attachments.
